SECURING RAILWAY-RAILS TO METAL SLEEPERS'.

Application filed April 27, 1887. Serial No. 236,381.

To all whom it may concern.-

Be it known that we, LOUIS PHILIBERT GOFFIN and EVARISTE VANRIET, bothresiding at Brussels, in the Kingdom of Belgium, have invented certainnew and useful Improve ments in Securing Ilailway-Rails to MetalSleepers. (for which we have received Letters Patent of Belgium, datedSeptember 24, 1886,

No. 74,626,) of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart thereof.

Our invention relates to a peculiar system of rail attachment for fixingrailway-rails to metallic longitudinal or cross sleepers; and itconsists of the use of an angularly-movable resting or bearing plate, A,in combination with two lock-pieces,l3 and G,and a wedge or key D. (SeeFiguresl and 3,which are respectively a sectional view on the line 1 2of Fig. 2 and a sectional view on the line 1 2 3 4. of Fig. 4.) Thesedifferent parts are arranged and combined in such a manner that when theresting or bearing plate A is placed under the rail-foot in a positionparallel thereto, Figs. 1 and 2, one of its lock-holes, of oblong form,shall coincide with a similar opening in the sleeper and permit of theintroduction of the outer lock-piece, B, which is then displaced untilit is almost in contact with the end of the lock-hole. Then, by means ofa lever, the sleeper and the resting-plate are ap plied against thelower surface of the rail. By then turning the resting-plate,by strikingit with a hammer until it is in its normal position perpendicular to therail, its angular motion is also imparted to the outer lock, B, which,by turning on its vertical axis, gradually and very tightly pinches therail foot and can no longer be removed.

In thenormal position of the resting-plate A, indicated in Figs. 3 and4., another hole in the same coincides with a corresponding hole in thesleeper situate 011 the inner side of the rail, and now permits of theforced introduction of the inner lock-piece, 0, whereby an energetictraction is exerted by means of the resting-plate A. on theexternallock-piece,and the pinching action of the same is increased.

The inner lock-piece is then entirely secured in its position by drivinga suitably-shaped key, 1), between the free part of its head and therestingplate until perfect fixing of the rail is effected.

The restingplate A, Fig. 3, may have a uniform'thiokness or a decreasingone, so as to present an inclined surface corresponding with theinclination to be given to the rails.

The outer lock-piece, 13, Figs. 3 and 5, resembles in its section adouble headed bolt suitably shaped for adaptingitself to the shape ofthe rail-foot. Its upper head is enlarged, so as to offer a sufficientsurface of contact. Its shank is at N, Fig. 5, of a section shown, Fig.7,so asto permit of free motion inthe hole in the sleeper, and at M,Fig. 5, of a section shown, Fig. 6, so as to compel the lock-piece tofollow the angular motion of the restingplate.

The inner lock-piece,0, Figs. 3 and 8,which may be replaced by any othercontrivance or look, if desired, possesses a single head of specialshape, so as to bear on one side against the rail-foot, whereas on theother side it leaves between it and the restingplate a certain openingfor the reception of the key D. The shank of this inner lock-piece isbent at its lower end, so as to bear against the under surface of thesleeper. The upper heads of the lock-pieces are made hollow or groovedout, so as to resemble in their section a T, whereby their weight isdiminished without diminishing their resistance.

The key D, Fig. 9, is straight or slightly inclined,and is wedgeshapedat one end and reenforced at the other. It is, moreover, provided withone or more ribs, which are engaged in corresponding slots in thelock-piece.

The arrangement described above permits of the rails being secured onthe external side Without displacing the same, and on theinner side bythe simple effect of the key.

When the rail ends are supported, lockpieces of larger dimensions may beemployed at thejoints, so asto secure two abutting rail ends at the sametime; or a lock-piece of greater dimensions may be used outside therails, and two lock-pieces on the inner side, one for each raildriveninto holes conveniently spaced apart.

Having fully described our invention, what we desire to claim and secureby Letters Patentis-- 1. The railwaytie, perforated as described,

and an angularly-movable resting plate, A, provided with two lock-holes,in combination with two lock-pieces,B C,and a wedge or key, D, thearrangement being such that in the first position of the resting-plate,parallel to the rai1,one of its lock-holes corresponds with a similaropening in the sleeper, so as to permit of the introduction of theexternal lockpiece, 13, whereas in its second position, transverse tothe rail, the other lock-hole coincides with a second opening in thesleeper, thus permitting the introduction of the inner lockpiece,O,substantially as described above, and shown in the annexed drawings.

2. The combination of the resting-plate A, with an external lock-piece,B, of such a section at N as will permit of its free motion in theopening of the sleeper and of such a section at M as will compel it topartake of the angular motion of the resting plate A, sub- 20 stantiallyas shown in the annexed drawings.

3. The combination of the resting-plate and the external lock-piece, B,with one or more lock-pieces, G, secured by means of a ribbed key, 1),and situate between the said key and 25 the rail, as specified.
